February 23 , 2025 11 hrs 0 min 26 0
  • Antimicrobial proteins isolated from oyster hemolymph (the equivalent of blood) can kill certain bacteria responsible for a range of infections.
  • The proteins can also improve the efficacy of conventional antibiotics against the problematic bacteria species.
  • Oysters are exposed to the high concentrations of diverse microorganisms in their natural marine environment.
  • Because of this, they have evolved strong immune defences.
  • The antimicrobial proteins in the hemolymph of Sydney rock oysters (Saccostrea glomerata) are particularly effective at killing Streptococcus spp. bacteria.
